Machine Wet End TRIZ Cases

Narrow cross-machine strips maintain uniform pressure, resolving pulsating flow and structural durability issues in web-forming machines.

Deformable pintles compress during processing to lower permeability and eliminate seam marking in papermaking dryer fabrics.

Multi-angle laser Doppler velocimetry determines jet velocity vectors to resolve measurement precision and control reliability trade-offs in papermaking.

A stock flow equalizer creates chaotic turbulence to mix fibrous stock, ensuring even chemical distribution and reducing usage costs.

A dewatering device removes water from the fibrous web via gentle compression between belts, preserving bulk structure while lowering drying costs.

A wet paper web transfer belt uses a polyurethane layer containing high and low roundness fillers to enhance adhesive and releasing properties.

Linear guides displace a tensioning roller relative to a deflection roller, creating an S-shaped strand angle under 40 degrees to reduce drive complexity.

Pressure waves from electrical discharges disrupt unidirectional fiber alignment, improving isotropic distribution and tear strength.

An adjustable foil apparatus uses a sliding mechanism to position the forming element relative to the forming fabric.

A tail pick-up pulley moves a fibrous web tail into position using mechanical force.

Porous polymer foam layers replace complex weaving processes to create irregular, high-volume tissue structures with uniform drainage.

Integrating a grinding member with the doctor blade eliminates production downtime caused by frequent belt removal and replacement for surface maintenance.

A triple-layer papermaking fabric uses binding yarns to interweave top and bottom layers, creating engineered drainage channels for efficient water removal.

A multiple mode headbox uses an adjustable roof to switch between high and low consistency flows, resolving uniformity trade-offs in versatile paper production.

A paper machine screen uses a repeating sub-repeat drawing-in pattern to assign warp threads asymmetrically.

Grouped weft yarns weave side-by-side to reduce interstices and air permeability, enabling high-speed production while minimizing contamination affinity.

Self-tapping connection adapters anchor a slotless deckle seal strip, eliminating labor-intensive fastener removal and reducing maintenance downtime.

Machine-side recesses collect liquid and contaminants to prevent roller slip while raised zones preserve static friction drive contact.

Measures humidity at distinct locations upstream and downstream of conditioning stations to resolve diagnosis reliability issues in paper making.
